Title: Improvements in or relating to magnetic recording sheets
IPC: G11B5/84
Filed: 1957-01-25
Abstract: 833,266. Magnetic sound records. TOKYO DENKI KAGAKU KOGYO KABUSHIKI KAISHA. Jan. 25, 1957 [Jan. 25, 1956; Jan. 28, 1956 (4); Feb. 14, 1956; May 19, 1956 (3)], No. 2799/57. Class 40 (2). A magnetic record sheet M (Fig. 4) has margins 17, 18 not coated with the magnetic film. The width " l" is equal to the chordal distance between any two adjacent heads (a, b, c) on a rotating carrier 1 (Fig. 1). The sheet may be stiffened by coating the marginal areas with a plastic material or pasting on metal foil or sheet plastic material. The sheet has printed information on the reverse side so that when placed magnetic film side downwards in a reproducing machine the printed information is visible through a transparent pressure plate. The information bearing side may be coated with a light-sensitive film for photographic reproduction. The sheet may be made larger than the pressure plate (see Fig. 22) so that an additional area is available for descriptive notes. A construction is described (Fig. 11) in which the sheet consists of a central layer of paper, plastic or metal foil 23 coated on one side with a magnetic film 14 and having a sheet of resilient material such as a filter paper 27 secured to the other side by thermoplastic adhesive 26. A second construction (Fig. 14) describes a transfer process for attaching a magnetic film to the back of a printed sheet or photograph 32. The transfer sheet 28 carries a magnetic film and a layer of thermoplastic adhesive 29. After heating and pressing to unite the magnetic film and the sheet 32, the transfer sheet 28 is stripped off. Conventional apparatus is described for piercing the sheet with filing and registration holes and trimming to size.

Abstract: 287,157. Siemens & Halske Akt.- Ges. March 18, 1927, [Convention date]. Track apparatus actuating signals on trains.-A magnetic system carried by the train and excited by alternating currents, and influenced by a track magnet to control a traincarried relay is so arranged that two magnetic fluxes pass over a number of airgaps or magnetic resistances arranged after the manner of a Wheatstone bridge connection in such manner that the bridge ratios are varied as the track magnet is passed. In the arrangement shown in Fig. 2, the exciting coils 2, 4 in series with the generator 5 cause two reversed fluxes 6, 7 to pass through the impulse coil 8 energizing the relay 9. At a track magnet 10, the flux 7 is increased and relay 9 becomes de-energized. The track magnet is provided with a short circuited winding closed bv a contact on the signal 13 by means of which the magnet is rendered ineffective as regards the train apparatus. Another arrangement described comprises a number of magnets at a distance apart on the train, the exciting winding of one being opposite the impulse winding of the adjacent magnet, all the exciting windings being in series with the generator and all the impulse windings in series with the relay winding.

Title: Improvements in or relating to the production of new therapeutically valuable quinoline derivatives
IPC: C07D215/40
Filed: 1943-03-01
Abstract: 1 : 2 : 3 : 4-Tetrahydro quinoline derivatives which posses anti-malarial activity are prepared by reducing a 6-alkoxy-8-amino-quinoline substituted on the amino nitrogen atom by an omega-dialkylaminoalkyl group or the anils obtained by condensing 6-alkoxy-8-aminoquinoline with compounds of the formul <FORM:0573958/IV/1> by any method known to be capable of converting a quinoline derivative into the corresponding tetrahydroquinoline derivative. Alternatively, the same compounds may be made by any process known for the preparation of the corresponding quinoline compounds using as a starting material a 1 : 2 : 3 : 4-tetrahydroquinoline compound instead of the unhydrogenated quinoline compound.  The reduction steps which may be used in the first modification of the present invention include catalytic hydrogenation, preferably with a Raney catalyst, electrochemical methods, or chemical methods such as sodium in ethyl or amyl alcohol or tin in hydrochloric acid.  The preferred product of the invention is 6 - methoxy - 8 - N(o  - diethyl - amino-a -methyl-butyl)amino-1 : 2 : 3 : 4-tetrahydroquinoline.  In examples: (1) 6-methoxy8-amino-quinoline is reduced catalytically in the presence of nickel to the tetrahydro compound which is then condensed with o -diethylaminob b  - diethoxypentane to form 6 - methoxy - 8 -( ? -diethylamino-a -methyl butylidene) amino - 1 : 2 : 3 : 4-tetrahydroquinoline which is reduced by sodium in alcohol to convert the butylidene group into a butyl group; (2) 6-methoxy-8-amino quinoline is reduced as before and the product condensed with 5 - diethylamino -2 : 2 - diethoxy-pentane and the condensation product reduced as before to 6-methoxy-8-N(o -diethylamino - a  - methyl butyl) - amino quinoline; (3) 6 - methoxy - 8 - N(o  - diethylamino - a  - methyl - butyl) amino quinoline is refluxed with sodium in alcohol to produce the corresponding 1 : 2 : 3 : 4 - tetrahydroquinolene; (4) 6 - methoxy - 8 - N(o -diethylamino-a -methyl butylidene)-amino quinoline is reduced with sodium in amyl alcohol to the corresponding 1 : 2 : 3 : 4-tetrahydroquinoline; (5) 6-methoxy-8-N(o -diethylaminoa -methyl butyl) amino quinoline is reduced catalytically with Raney nickel in dioxane solution to the corresponding 1 : 2 : 3 : 4-tetrahydroquinoline; (6) 6-methoxy-8-N(o -diethylamino - a  - methyl butyl) amino quinoline is reduced by tin in concentrated hydrochloric acid solution to the corresponding 1 : 2 : 3 : 4-tetrahydroquinoline.  A sample has been filed under Sect. 2 (5) of 6 - methoxy - 8 - N(o  - diethylamino - a  - methyl butyl) amino - 1 : 2 : 3 : 4- tetrahydroquinoline prepared by condensing 1 : 2 : 3 : 4-tetrahydro6 - methoxy - 8 - aminoquinoline with 5 - diethyl - amino-2 : 2-diethoxypentane in the presence of ammonium chloride in a hydrogen atmosphere, and then reducing the condensation product with sodium in alcohol.

[Class 20 (ii).] A telescopic pit-prop of the type in which an upper member is adjusted on a lower section bar member by means of a transverse wedge traversing the web of the section-bar has the upper member 7 formed with depending legs 6 which straddle the web 3 of the lower member, the flanges of which are bent around at 2 to enclose the legs. The upper member is connected by pin and slot 9 and 11 to the lower member, the top edge of which is inclined to coact with the wedge 12. The upper member may comprise a flat bar 7 with a strip of metal bent into the form of a U welded to it to form the legs, or may be formed of a T-bar with legs riveted to the flange. The angle of the wedge may be such that the wedge tends to come out under pressure, in which case a locking bar 15 embracing the top of the lower member, the upper member, and one end of the wedge is used to retain the wedge in position. To increase the range of adjustment, the wedge may be formed with stepped surfaces.

When a complete row has been formed along the edge a ram 22 actuates a displacement bar 18 to move the row across the pallet. This is repeated row by row until a complete layer has been formed when the ram 22 is moved to engage jacks 28, Fig. 5, which through levers 30 raise wheels 32 and force the loaded pallet 8 over toggles 33, Fig. 3, which then support them and allow the next pallet 8b to be loaded. These steps are repeated until a complete stack has been formed in the wagon. To unload the wagon the bar 18 and its supports 35 are dismantled the latter being inclined to form a ramp over which the lowest layer of bales is pushed step by step by prongs 36 on a bar 37 actuated by the ram 22 in a third position. As each pallet is unloaded the toggles 33 are released to allow the pallet above to fall to the unloading position.
